          Abstract

          A total of 57 infants hospitalized with rotavirus disease were included in this study. The children were randomly divided into the study’s two treatment groups: three days of the oral administration of (i) a probiotics formula containing both Bifidobacterium longum BORI and Lactobacillus acidophilus AD031 ( N = 28); or (ii) a placebo (probiotic-free skim milk, N = 29) and the standard therapy for diarrhea. There were no differences in age, sex, or blood characteristics between the two groups. When the 57 cases completed the protocol, the duration of the patients’ diarrhea was significantly shorter in the probiotics group (4.38 ± 1.29, N = 28) than the placebo group (5.61 ± 1.23, N = 29), with a p-value of 0.001. Symptoms such as duration of fever ( p = 0.119), frequency of diarrhea ( p = 0.119), and frequency of vomiting ( p = 0.331) tended to be ameliorated by the probiotic treatment; however, differences were not statistically significant between the two groups. There were no serious, adverse events and no differences in the frequency of adverse events in both groups.

          Global Causes of Diarrheal Disease Mortality in Children <5 Years of Age: A Systematic Review

          Claudio F. Lanata, Christa Fischer-Walker, Ana C. Olascoaga … (2013)
          Estimation of pathogen-specific causes of child diarrhea deaths is needed to guide vaccine development and other prevention strategies. We did a systematic review of articles published between 1990 and 2011 reporting at least one of 13 pathogens in children <5 years of age hospitalized with diarrhea. We included 2011 rotavirus data from the Rotavirus Surveillance Network coordinated by WHO. We excluded studies conducted during diarrhea outbreaks that did not discriminate between inpatient and outpatient cases, reporting nosocomial infections, those conducted in special populations, not done with adequate methods, and rotavirus studies in countries where the rotavirus vaccine was used. Age-adjusted median proportions for each pathogen were calculated and applied to 712 000 deaths due to diarrhea in children under 5 years for 2011, assuming that those observed among children hospitalized for diarrhea represent those causing child diarrhea deaths. 163 articles and WHO studies done in 31 countries were selected representing 286 inpatient studies. Studies seeking only one pathogen found higher proportions for some pathogens than studies seeking multiple pathogens (e.g. 39% rotavirus in 180 single-pathogen studies vs. 20% in 24 studies with 5–13 pathogens, p<0·0001). The percentage of episodes for which no pathogen could be identified was estimated to be 34%; the total of all age-adjusted percentages for pathogens and no-pathogen cases was 138%. Adjusting all proportions, including unknowns, to add to 100%, we estimated that rotavirus caused 197 000 [Uncertainty range (UR) 110 000–295 000], enteropathogenic E. coli 79 000 (UR 31 000–146 000), calicivirus 71 000 (UR 39 000–113 000), and enterotoxigenic E. coli 42 000 (UR 20 000–76 000) deaths. Rotavirus, calicivirus, enteropathogenic and enterotoxigenic E. coli cause more than half of all diarrheal deaths in children <5 years in the world.

            Lactobacilli and Bifidobacteria Promote Immune Homeostasis by Modulating Innate Immune Responses to Human Rotavirus in Neonatal Gnotobiotic Pigs

            Anastasia N. Vlasova, Kuldeep S. Chattha, Sukumar Kandasamy … (2013)
            The effects of co-colonization with Lactobacillus rhamnosus GG (LGG) and Bifidobacterium lactis Bb12 (Bb12) on 3-dose vaccination with attenuated HRV and challenge with virulent human rotavirus (VirHRV) were assessed in 4 groups of gnotobiotic (Gn) pigs: Pro+Vac (probiotic-colonized/vaccinated), Vac (vaccinated), Pro (probiotic-colonized, non-vaccinated) and Control (non-colonized, non-vaccinated). Subsets of pigs were euthanized pre- [post-challenge day (PCD) 0] and post (PCD7)-VirHRV challenge to assess diarrhea, fecal HRV shedding and dendritic cell/innate immune responses. Post-challenge, Pro+Vac and Vac groups were completely protected from diarrhea; protection rates against HRV shedding were 100% and 83%, respectively. Diarrhea and HRV shedding were reduced in Pro compared to Control pigs following VirHRV challenge. Diarrhea scores and virus shedding were significantly higher in Controls, compared to all other groups, coincident with significantly higher serum interferon-alpha levels post-challenge. LGG+Bb12 colonization ±vaccine promoted immunomaturation as reflected by increased frequencies of CD4, SWC3a, CD11R1, MHCII expressing mononuclear cells (MNCs) and conventional dendritic cells in intestinal tissues and blood post-challenge. Colonization decreased frequencies of toll-like receptors (TLR) 2 and TLR4 expressing MNCs from vaccinated pigs (Pro+Vac) pre-challenge and increased frequencies of TLR3 expressing MNCs from Pro pigs post-challenge, suggesting that probiotics likely exert anti-inflammatory (TLR2 and 4 down-regulation) and antiviral (TLR3 up-regulation by HRV dsRNA) actions via TLR signaling. Probiotic colonization alone (Pro) increased frequencies of intestinal and systemic apoptotic MNCs pre-challenge, thereby regulating immune hyperreactivity and tolerance. However, these frequencies were decreased in intestinal and systemic tissues post-challenge, moderating HRV-induced apoptosis. Additionally, post-challenge, Pro+Vac and Pro groups had significantly decreased MNC proliferation, suggesting that probiotics control excessive lymphoproliferative reactions upon VirHRV challenge. We conclude that in the neonatal Gn pig disease model, selected probiotics contribute to immunomaturation, regulate immune homeostasis and modulate vaccine and virulent HRV effects, thereby moderating HRV diarrhea.

              Bacterial, viral and parasitic enteric pathogens associated with acute diarrhea in hospitalized children from northern Jordan.

              S Bretagne, N Strockbine, A Shurman … (2000)
              To determine the etiology of acute diarrhea in Jordanian children under 5 years of age, we examined stool samples from 265 children admitted to the pediatric ward at Princess Rahma Hospital for Children, Irbid, Jordan, for parasites, rotavirus and enteric bacteria. Using both traditional and molecular diagnostic techniques, we detected enteropathogens in 66.4% of patients with diarrhea. A single enteric pathogen was detected in 50.9% of the children, and multiple pathogens were detected in 15.5%. The prevalence of enteropathogens identified was as follows: rotavirus (32.5%), enteropathogenic Escherichia coli (12.8%), enteroaggregative E. coli (10.2), enterotoxigenic E. coli (5.7%), Shigella spp. (4.9%), Entamoeba histolytica (4.9%), Salmonella spp. (4.5%), Campylobacter jejuni/coli (1.5%), Cryptosporidium spp. (1.5%), enteroinvasive E. coli (1.5%), eae-, Ehly-positive E. coli (0.8%), Giardia lamblia (0. 8%) and Yersinia enterocolitica (0.4%). No Vibrio cholerae, Shiga toxin-producing E. coli, microsporidia, adenovirus or small round virus were detected. Findings from this study demonstrate that rotavirus and several types of diarrheagenic E. coli, which are not screened for during routine examinations of stool samples in public health laboratories, were the most frequently detected enteropathogens in these children. Our findings highlight the value of using a combination of traditional and molecular techniques in the diagnosis of diarrheal disease in this population.
